A man shopping in the Twin Cities says he'll never give to the charity again after a bell-ringer harassed him as he left a store. The Salvation Army tells the Star Tribune that, if it can substantiate the man's report, it will make sure the offender never rings the bell again.

The Minnesota-based retailer has changed its mind after banning bell-ringers outside stores. An executive had said the company feared allowing bell-ringers would open the floodgates to anyone who wanted to use store property.

Minneapolis-based U.S. Bancorp, parent company of U.S. Bank, and the Salvation Army have teamed up to create a new iPhone app that lets volunteers sign up for bell-ringing time slots at 400 Twin Cities kettles this holiday season, according to a company news release.
